Coupling of vibro-acoustic waves with premixed flame

Résumé

We investigate the coupling between a premixed flame freely propagating inside a Hele-Shaw burner and the mechanical vibrations of the burner structure. The combustion chamber deformations are not only able to damp the classical thermoacoustic instabilities but they can also trigger a new oscillating combustion instability. We demonstrate that the flow oscillations induced by the burner vibrations can be used to control the shape of the flame surface, by damping the Darrieus-Landau dynamics, or by triggering Faraday-like waves.
